Wi-Fi technology connects sensor-based things that operate with small batteries, and allows them to access the Internet from anywhere at any time and perform networking. It has become a critical element in many areas of daily life and industry, including smart homes, smart factories, smart grids, and smart cities. The Wi-Fi-based Internet of things is gradually expanding its range of uses from new industries to areas that are intimately connected to people's lives, safety, and property. Wi-Fi technology has undergone a 20-year standardization process and continues to evolve to improve transmission speeds and service quality. Simultaneously, it has also been strengthening power-saving technology and security technology to improve energy efficiency and security while maintaining backward compatibility with past standards. This study analyzed the security vulnerabilities of the Wi-Fi power-saving mechanism used in smart devices and experimentally proved the feasibility of a battery draining attack (BDA) on commercial smartphones. The results of the experiment showed that when a battery draining attack was performed on power-saving Wi-Fi, 14 times the amount of energy was consumed compared with when a battery draining attack was not performed. This study analyzed the security vulnerabilities of the power-saving mechanism and discusses countermeasures.

电池耗电攻击和针对节能无线局域网设备的防御。

Wi-Fi技术将使用小型电池供电的基于传感器的物体连接起来，并允许它们随时随地访问Internet并进行联网。它已成为日常生活和工业中许多领域的关键要素，包括智能家居，智能工厂，智能电网和智能城市。基于Wi-Fi的物联网正在逐渐将其用途范围从新兴行业扩展到与人们的生活，安全和财产紧密相关的领域。Wi-Fi技术已经经历了20年的标准化过程，并不断发展以提高传输速度和服务质量。同时，它还一直在加强节能技术和安全技术，以提高能源效率和安全性，同时保持与过去标准的向后兼容性。这项研究分析了智能设备中使用的Wi-Fi节能机制的安全漏洞，并通过实验证明了商用智能手机上的电池耗电攻击（BDA）的可行性。实验结果表明，在节电的Wi-Fi上执行电池耗尽攻击时，与未执行电池耗尽攻击时相比，消耗了14倍的能量。该研究分析了节电机制的安全漏洞，并讨论了对策。与没有执行电池耗尽攻击时相比，消耗了14倍的能量。该研究分析了节电机制的安全漏洞，并讨论了对策。与没有执行电池耗尽攻击时相比，消耗了14倍的能量。该研究分析了节电机制的安全漏洞，并讨论了对策。
